Specification of Letters Patent.

Application filed March 2, 1914. Serial No. 822,004.

To all whom it may concern:

Be it known that I, CHARLES M. Mo- LEOD, a citizen of Great Britain,residing at New York, in the county of New York and State of New York,have invented certain new and useful Improvements in Processes forTreating Textile Fabrics; and I do hereby declare the following to be afull,

clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

My improved process of printing textiles has for its object theproduction of woolen fabrics bearing an ornamental design of apermanence and appearance hitherto not attainable. More especially, bythe process to be hereafter described, I am enabled to produce a printedwoolen blanket with a permanent and durable design which is superior inappearance to a woven design, as I am enabled to secure a variety ofcoloring not attainable in a purely woven pattern.

To produce my improved printed fabric I proceed as follows I prepare awoolen fabric in' the ordinary manner by weaving and then subject thisrough unfinished cloth to a process of sulfurization, that is to a bathof sulfurous acid or sulfur dioxid gas which tends to bleach the fiberand prepare same for the subsequent process of printing;

This fabric in its ordinary form be ore napping has a thickness ofapproximately one fourth of an inch and presents a felted roughenedsurface. This cloth is then printed in the ordinary manner either byblock printing or by spray printing, care being taken to use permanentcolors which will not be discolored b the subsequent finishing processand which are not changed by the woolen fiber. In order that the designmay be' impressed upon the fabric throughout its thickness, it isrequired that the printing be applied with considerable necessary werethe printing on the surface merely. After the printing in one or morecolors is completed, the cloth is finished by steaming which tends todistribute and fix the color uniformly throughout the thickness of thefiber. Lastly the napping process is resorted to, so that a fabric ofapproximately one fourth of an inch thickness will attain double thisthickness and the soft appearance of the ordinary blanket. By printingthe fabric before the napping operation,.a softness of outline and adelicacy of tone is obtained which it is not possible to obtain byprinting on the napped fabric. This enables me to reproduce on blanketsthe emblem or crest of societies, clubs, hotels, etc., in theirpropercolors and also to produce borders on blankets which will be in harmonywith the decorations of the room in which they will be used.

I am aware that it is old in the art to print textiles by means of blockprinting or spraying, but what I have discovered is the art of sotreating blanket fabrics so as to produce clear and permanent designs inone or more colors, such designs penetrating the entire thickness of thefabric so that the design appears in a uniform manner throughout thesame.

What I claim is: I

1. A process of treating textile fabrics by block printing the woolenfabric and subsequently napplng the same.

2. A process of treating Woolen fabrics by block printing said clothwith inks not affected by the woolen fiber, then napping said fabric.

In testimony whereof I afiix my signature in presence of two witnesses.
